EYELETING-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 451,361, dated April 28, 1891.

Application filed April I6, 1890.

To all wiz/m, t may concern:

Be it known that I, FRANK BEAN, of Medford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Setting-Machines, of

which the following is a specication, reference being had tothe accompanying drawings, in which- Figure 1. is an elevation of a machine emxo bodying my invention. Fig. 2 is a View of a portion of the brush-rotating attachment detached for greater clearness. Fig. 3 is a sectional view enlarged on line 3 3 of Fig. l, showing a portion of the chute, nail-throat,

i5 and a portion of the driver. Fig. 3 is a sectional view on line 3f* 3 of Fig. 3. Fig. 4 is a sectional view on line 4 4E' of Fig. l.

My invention relates to machines for driv- -ing and setting metallic fastenings, the obzo ject of my invention being to produce an improved machine for this purpose.

One feature of my invention'consists in the combination of the brush and a pedal or its equivalent in such Wise that the brush is ro- 2 5 tated whenever the machine is in operation'.

Another feature of my invention is the combination of the driver and anvil-bar by a yielding anvil-locking devicefhereinafter set forth.

In the drawings, a is the usual inclined reservoir provided with a rotary brush.

a is the brush spindle or carrier.

c2 is the shaft through which the brush spindle or support is moved to rotate the brush, and p is the usual pedal.

In order to get a constant and certain supply of fastenings in the chute b, I have found it highly advantageous to keep the brush moving when the machine is in operation, and

4o in order to do this in machines operated by.

a pedal or the like I connect the brush spindle or support with the pedal in such wisethat the brush is rotated with each complete movement of the pedal-that is, When the pedal is depressed the brush is partially rotated, and when the pedal returns to its highest position the complete rotation of the brush is effected. The advantage of so doing is that the fastenin gs are frequently swept from 5o the outlet into the chute, where they tend to Serial No. 348,258. (No model.)

lodge and clog, owing to the inclination of the bottom of the reservoir. The best means known to me for connecting the pedal and brush are the following: Shaft a2 is provided with loose pulleys a3 a3, each carrying a pawl a4. Pawls a4 engage ratchets c5 fast on shaft a2. A belt a6 is fast at each end to pedal p, and passes thence over pulleys a3 a3 and 'a pulley a7, secured in a suitable bracket d8, in this case mounted on the frame of the machine. When the pedal is depressed, the pulley is coupled to the shaft a2 through its pawl and ratchet, and when the pedal rises this pulley is uncoupled from the shaft and the other pulley coupled to the shaft, so that the brush is rotated not only when the pedal is depressed, but also when it is raised.

It is necessary to lock the anvil d when thev fastening is driven, the anvil rising and falling to serve as a presser-foot. The anvilbar d is mortised at d2 to receive a lockingbar d3, which is shot forward into the mortise to lock the anvil while the fastening is being clinched, and is Withdrawn when the driver rises to release the work. Anvil-bar d is provided with a spring d4, which tends to keep the anvilbar in its highest position, and the anvil-bar is fulcrumed to a lever d5, which is engaged by a lever d6, fulcrumed at C17, and connected to a rod d8, which is secured to the rod (Z9, connecting the driverlever d10 and pedal p. Lever d6 has a forked arm du, which receives within its fork a block C112, through which passes the lockingbar cl3, the block C112 serving as an abutment for a spring d, interposed between the block d12 and an abutment du on the locking-bar. When the treadle is depressed to bring down the driver, the free end of lever d6 moves away from the inner end of the lever d, and spring d4 then raises the anvil-bar, bringing mortise d2 into the path of the locking-bar, which is shot forward by the movement of arm d into the mortise. The mortise has aninclined Wall, and the forward end of the locking-bar is beveled to adapt the machine for work Varying in thickness, and the connections between the locking-bar and lever d should be a yielding connection to prevent the lockingbar from being shot forward positively and IOO so endangering the machine, as will be elear to all skilled in the art.

The throat b (shown in the drawings) is removable, being secured in a bracket b2 on the head of the machine and to the chute and is therefore formed with a chute-section lf. The upper end of the throat is best fiared slightly, as shown. The driver is indicated by b". The throat t is an adjustable throat having an enlarged passage t. These two features of my invention are set forth and described in my applieatio11,Se1'ial NO.3IS,257, of even date herewith, and are not hereby abandoned, but are claimed in said application. y l
